Response of 'Tifdwarf' bermudagrass to seaweed-derived biostimulants

Abstract

'Tifdwarf' hybrid bermudagrass [Cynodon dactylon (L) Pets. x C. transvaalensis Burtt-Davy] grown on a putting green in southern Florida was treated for 2 years with two seaweed-derived biostimulants, Kelpak and PanaSe Plus. No significant treatment differences were observed in turfgrass quality (44 observation dates) or root weights (eight collection dates). There was only 1 of 22 collection dates for clipping weights that obtained a significant difference among treatments. Although the biostimulants did not enhance plant growth or quality, neither were they harmful to the turfgrass.
